SPECIFICATION formingpart of Letters Patent No. 650,563, dated. May 29, 1900.

Application filed June 27, 1899. Serial No. 722,071. (No model.)

To LZZ whom, t 77mg/ concern:

Be it known that I, JOSEPH E. MORRIS, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Tater-Filters; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

This invention relates to improvements in water-filters; and it consists in the novel arrangement and construction of the parts hereinafter set forth and described.

In the drawings, Figure l is a vertical sectional view of a filter constructed in accord ance with this invention. Fig. 2is a crosssection of the filter, taken on the line .fr .fr in Fig. l. Fig. 3 is a diagrammatic view of the arrangement of a number of filters constructed in accordance with this invention arranged and adapted to supply a common draw-off faucet. Fig. 4 is a detailed view in plan of the means employed by me for securing the cover.

The objects of the present invention are to provide a filter having a capacity within the filteringtube to supply a desired quantity of filtered water; further, to provide a coustruction by means of which the outer surface of the filtering-tube maybe cleansed and the dirt carried away by the Waste-pipe; further, to so construct and arrange the lter upon a supply-pipe that the filtered water and the unfiltered water may be drawn through the same faucet.

To facilitate the description of the present invention with reference to the drawings, I have assigned the letter A to designate the filtering-tube. This in the present invention is constructed of the usual material, but is shaped to form a large interior chamber. It is domed at the top and is mounted about a central tube B. The central tube B is mounted upon the circular holding-plate C, which is provided with an upward-turned flange O to receive and guide the filtering-tube. Between the lower edge of the filtering-tube and the surface of the holding-plate O is inserted a suitable gasket O2. The central tubo B is D forms the covering for the chamber E and rests on the gasket D', which rests on the upper edge of the holder E and the casing F. The cover D is secured in position by the ring D2. This encompasses the casing F above the lugs F3, the lower portion of the ring resting upon the said lugs F3 when the cover is removed and under the lugs F4, which are extended outward from the side of the casing F. The upper portion of the ring D2 is provided with hook-like extensions D3., which when the cover D is removed rest against the outer surface of the lugs F". The cover is provided with depending extensions D4,which have outwardly-extending lugs D5, adapted to pass downward between the extensions D3 on the ring. These lugs D5 are slightly inclined on top, so as the extensions D3 are forced over them the cover is drawn down hard on the gasket D. To draw the ring around over the lugs D5, there is provided a socket D6 in the ring to receive the end of a Spanner-wrench.

When the cover D is removed, the extensions D3 rest in line with the lugs F4. The cover is placed in position by the extensions D4 being inserted between the lugs F4 when the lower portion of the inclined surface of the lugs D5 are below vthe extensions D3 of the ring D2. By turning the ring to force the extensions D3 over the lugs D5 the cover D is drawn down tightly on the gasket D and the chamber E is effectually closed.

The tube B is provided With an internallythreaded perforation where it passes through the cover D. Into this is screwed a shank carrying the handle'B4 and serves to support the tightening-nut B3. When this nut B3 is screwed down hard, the tube B and the filtering-tube A are clamped firmly in position. When the said nut B3 is loosened, the said IOO parts are loosened from the cover D and may be rotated by means of the handle B4 upon the coned pivot C3, which is extended down from the plate C. By means of this constru ction the cleaning above mentioned is effected. The side wall of the holder' E is perforated, as shown in the drawings. These perforations E2 are disposed vertically in the holder E. By reason of this construction when the water is drawn from out of the inner chamber E, formed by the holder E', the water which fiows into this chamber is drivenjn small jets against the surface of the tube A. p

Itis to permit the water to be drawn from the chamber E that I have providedV the pipe H. This pipe H is provided with a stop-cock l-I and is constructed to enter the stop-cock I', which is a usual two-way faucet. When it is desired to cleanse the filtering-tube A, all that is required is to turn the stop-cock H', so that the Water will iiow. The water from the chamber E, being unobstructed, Hows rapidly and freely from the chamber, when the Water entering the chamber through the perforations in the side walls thereof does so under pressure, with the effect as hereinbefore mentioned. The nut B3 is loosened and the tube A is rotated slowly, presenting` all the surface of the tube to the jets being thrown through the perforations E2 and in this manner clearing the tube A from the outside deposits due to filtration.

As the stop-cock II is designed to be used whenever a large volume of unfiltered water is desired, as in drawing the Water for washing or cooking purposes, this arrangement and construction has the effect that the tube A is being frequently cleansed by reason of thefact that the unfiltered water is drawn frequently through the pipe II.

It is vto draw the filtered water which has passed to the inner chamber of the tube A that I have provided the pipe J. This pipe penetrates the side walls of the casing F and. the holder E and is provided at its inner end with a cup-like construction to receive the coned pivot C3. The tube B is provided with the perforatious B, so that the water contained within the inner chamber of the tube A finds egress therefrom.

Near the upper end of the tube B, I have provided a perforation B8, the lower end of which is coned. Vithin the tube B, I place a float K, the upper end of which is coned to fit within the lower end of the perforation. 1When now the Water is introduced into the filter, the float K is raised to seat its upper coned end within the lower end of the perforation BS, so that the water will not rise upward through the perforation. Vhen, however, the water is drawn from the filter, the float K will be lowered. The perforation BB is then open toadmit air into the tube B and through the perforations B7 into the inner chamber formed in the filtering-tube A. By this means air is admitted over the top of thev When a known or large quantity of filtered Y water is desired, the stop-cock I' is turned on, while't-he stop cock H is closed, and a receptacle is placed beneath the faucet I. The filtered water will then run more or less slowly into the receptacle placed to receive it. Ifv during this time, however, it is desired to use the unltered water, this may be arrived at by closing the stop-cock I', removing the receptacle containing the ltered water, and

opening the stop-cock H', when the usual flow of unfiltered water under the usual pressure will be drawn.

Having thus described this invention, it is claimed-- l. In a water-filter, the combination with a filtering-tube; of an outlet-pi pe lead ing from the interiorof the said filtering-tube and provided with a faucet; a containing-tube for the said filtering-tube, the walls of which are perforated; a casing connected to the watersupply and surrounding the said containingchamber, substantially as described.

2. In a water-filter the combination with a filtering-tube; of a containing-chamber for the said filtering-tube, having a series of perforations in the wall thereof; a casing connected to the water-'supply and surrounding the said containing-chamber; suitable discharge-pipes leading from the interior of the filtering-tube and from the containing-chamber to discharge into a common faucet; and suitable means for controlling the iiow through both discharge-pipes; substantially as described.
